He published a
Latin version of the
Gesta Danorum in 1534, entitled
Saxonis grammatici Danorum historiae libri XVI. In 1542, he attempted to print the first
Quran in
Latin, edited by
Theodor Bibliander from a translation made by
Robert of Ketton in Spain in 1142–1143. This Quran was part of
a collection of Islamic works commissioned by
Peter the Venerable. The municipal authorities imprisoned Oporinus for a short while, but a letter from
Martin Luther convinced them to permit the printing. Luther and
Philip Melanchthon provided introductory essays for the edition. The most important publication of his workshop was the anatomical atlas
De humani corporis fabrica by the humanist physician
Andreas Vesalius, in 1543. In October 1546 a book on the assassination of the Spanish Protestant
Juan Díaz, entitled
Historia vera de morti sancti viri Ioannis Diazii Hispanics [...] by Claudium Senarclaeum, was published by his workshop, which is attributed to
Francisco de Enzinas. In addition, his press published numerous polemical theological works, classics, and historiographical works. His fine knowledge of ancient languages served the quality of consistently correct textual editions. Oporinus later printed a work on church history by
Matthias Flacius Illyricus:
Catalogus testium veritatis (1556) and the first eleven (1559–1567) of
Wigand's thirteen
Magdeburg Centuries. In 1559 he published the complete
editio princeps of
Diodorus Siculus'
Bibliotheca historica. Before he died, he planned to publish the first Bible in the Spanish language, for which
Casiodoro de Reina paid 400 guilders in advance. But Oporinus died before the bible was able to go into print. == Oporinus' mark ==
